Helga Veronica Tinnesand

Helga Veronica Tinnesand serves as Associate Professor at the University of South-Eastern Norway (USN), affiliated with the Institute for Nature, Health and the Environment within the Faculty of Technology, Natural Sciences and Maritime Studies. Based at Campus Bo, she holds critical administrative roles in research education, ethics oversight, and data management while maintaining an active research program in chemical ecology.

Her research focuses on olfactory communication in nocturnal mammals, particularly Eurasian beavers and European badgers. Using advanced chemical analysis, she investigates how gland secretions convey information about individual identity, social status, group membership, and kinship. Her work reveals complex signal layers in anal and subcaudal gland secretions that enable territory defense, social coordination, and reproductive strategies.

Analysis of her publications (2009-2020) shows consistent contributions to understanding chemical signaling mechanisms. Key themes include: territorial assessment strategies, context-dependent intruder responses, multi-layered chemical signatures, and methodological rigor in GC-MS data processing. Her research bridges analytical chemistry and behavioral ecology to decode animal communication systems.

Scientific Recognition:

• 3rd Prize in Poster Competition at 5th International Beaver Symposium (Lithuania, 2009)
• Multiple presentations at international conferences including Chemical Signals in Vertebrates and International Behavioral Ecology Congresses

As research education coordinator, she supervises graduate students in ecological fieldwork and chemical analysis techniques. Her international collaborations (UK, Germany, Australia) provide students with cross-institutional research opportunities. Her methodological publications establish best practices for chemical ecology data interpretation, enhancing research reliability in the field.

Her laboratory work centers on chemical analysis of mammal secretions using gas-chromatography mass spectrometry, supported by chemometric data analysis to extract biological meaning from complex chemical profiles. This approach has revealed how animals encode social information in scent marks at individual and group levels.
